Everyone should have read this book! At first I was quite reluctant to read it because I was expecting a technical book but not at all! The presentation of different personalities is clear and factual, it's really interesting to see how these people understand. What I particularly liked about this book is that the authors are still in pragmatism without falling into the judgment. Finally, the book is full of case histories and anecdotes that make it very lively book. In short, you will understand, I highly recommend reading it!
